# Railbird Pool vs World Invite

The clearest difference is rating: World Invite at 5.0 against Railbird Pool's 4.2. Railbird Pool's advantage is update cadence (weekly vs every 2 months) and monetization model (free vs freemium). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Railbird Pool sells 4 in-app purchases, starting at $10.99 per month and World Invite sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
